Cooling fan diagnosis GE JVM1443WK

I think my cooling fan inside the oven failed.
I can not find any info on it to test to see if it is any good. Has three terminals on it. One has a single black wire, the other has a black wire and orange wire, and the third has a white wire and a pink wire to it.
Not getting continuity from the terminal with the single black wire to either of the other two terminals, but am getting continuity between those two terminals

That is not the same fan I'm talking about. NOT the vent fan. The cooling fan that comes on when the oven is started. I need to know hot to diagnose if it is good or not.That is not the same fan I'm talking about. NOT the vent fan. The cooling fan that comes on when the oven is started.

I'm not going to replace a fan motor without confirming that the motor is bad. The motor is special order and NOT returnable.I'm not going to replace a fan motor without confirming that the motor is bad. The motor is special order and NOT returnable.

I have been having problems with two different microwaves in two locations. One, a Goldstar, and the other this GE. I found the problem on the GE. One of the wires to the cooling fan did not have a good connection to the quick connector. I fixed that and it's working fine now. The Goldstar, it turns out, is just the door switch on top. But what I did notice is that there is no cooling fan in the Goldstar. It uses the ventor fan. And the cabinet behind the control in the Goldstar is empty, especially comparred to the GE, which is full and hard to even get your hand in. It helps that I found a wiring diagram for both units. The GE diagram was tucked in a black envelope away from the electronics. (Hmmmmm) The Goldstar had their's tucked right below the control on the inside.I have been having problems with two different microwaves in two locations. One, a Goldstar, and the other this GE.

Did you READ the "Experts" solutions?One had no idea of a second fan motor and the other said to replace the fan or call a service technician. I repair Heating and Air Conditioning equipment for a living, and in the last week I spent a lot of time trying to fix my microwave. I did fix it and it had NOTHING to do with the so called "Expert" advice given. There was a bad crimp of an electrical connector to the wire. Also, one of your "experts" can't even spell properly!If I had followed one of your "expert's" advice, I'd be out about $85 and still have a microwave that doesn't work.If you feel this is fair, then I feel it fair to post this as a reply to your experts advice.Did you READ the "Experts" solutions?

Automatic fan feature protects the microwave from too muchheat rising from the cooktop below it. It automatically turns on atlow speed if it senses too much heat.If you have turned the fan on you may find that you cannot turn itoff. The fan will automatically turn off when the internal parts arecool. It may stay on for 30 minutes or more after the cooktop andmicrowave controls are turned off

There
should be a "mini-manual" (tech sheet) hidden inside the unit
behind the
control panel or hidden on the left side behind the grille, which is
very helpful when troubleshooting, testing, and locating
components.

At
our Web site, we have a video
available showing how to remove a typical
over the range control panel assembly in under 5 minutes.

You can find
helpful exploded view diagrams and order parts by entering your full
model number from the tag on the oven here.

On some Samsung/GE models, the turntable motor and stirrer motor are powered
off a tap on the internal cooling fan motor and in such cases they will
be marked "21V AC".

When I say internal
cooling fan, I do not mean the hood vent exhaust fan which you can turn
on and off manually.

I'm instead talking
about the internal fan which comes on automatically whenever you
microwave.

It is vital that the
cooling fan runs, or the turntable and stirrer won't work, and magnetron will soon be destroyed.

A quick
test is to remove the stirrer cover in the ceiling of the oven. The
owner's manual tells you how, and you can download that here.

Then run the oven for several seconds with a cup of water inside while
watching the stirrer blade in the top. It should turn very slowly.

If it does not turn or is jerky, it or the cooling fan is not working.

Also, we have a sound clip of what a microwave should sound like when the cooling fan and everything else is working here.

The cooling fan's absence will be notable after you hear the clip.

The turntable system
otherwise consists of the motor, the coupler, the turntable support with rollers,
and the tray.

You can see and hear a video of how a turntable motor should
sound when you rotate it by hand.

If
the cooling fan is good, but yours won't rotate
or it sounds like it's grinding, etc., you may have a bad motor or
plastic coupler.

To
replace either, you need to unplug power, then remove the bottom cover
of the oven.

Accessing some parts may require you to pull the oven from thew wall and remove the cover.

If
so, the installation instructions are very handy, and it's best to have
two people since the microwave can be heavy and awkward.

CONTROL BOARD HAD FAILED your magntron is starting but the cooling fan for it is not , the control relays that control them enegerize at the same time . if not this is what happens . repair is very costly . ge has had probles with there microwaves for years , when you replace think about another brand . good luck

Assuming that your internal cooling fan is working, I would suspect that your magnetron is failing.

I would check the cooling fan, then suspect the magnetron.
